I'm using Qlogic Product SCSI/RAID PCI Adapter ISP10160A Ultra3 SCSI processors. But I dont know how to configure it to work with SCSI & RAID Hard Disk. When my OS(Windows 98 & XP) finished boot, My SCSI disk drive does not display in My Windows OS. My SCSI Disk is Quantum Atlas V 3.5 Series. Could You Please Help me out how to configure my SCSI adapter so that I Can see the drive letter of the SCSI Disk in My OS(Windows). Feature Summary The ISP10160A/33 supports a 33-MHz, 64-bit PCI host bus interface with a 264 Mbytes/sec maximum PCI transfer rate. Compliance with PCI Local Bus Specification rev 2.1 Compliance with ANSI draft T10/1302D SCSI-3 Parallel Interface (SPI-3) Supports Ultra3 (Fast-80) SCSI SCSI feature set: dual transition, CRC, domain validation Compliance with PCI Bus Power Management Interface Specification revision 1.0 (PC98) Supports one wide Ultra3 (Fast-80) SCSI channel Up to 160 Mbytes/sec parallel SCSI transfer rate Supports single-ended, low voltage differential (LVD) SCSI SCSI initiator and target modes of operation Onboard RISC processor to execute operations at the I/O control-block level from the host memory Supports PCI dual-address cycle (64-bit addressing) No host intervention required to execute SCSI operations from start to finish Simultaneous, multiple logical threads JTAG boundary scan support Description The ISP10160A supports single channel, Ultra3 SCSI functionality and is pin compatible with QLogic’s ISP12160 and ISP12160A Ultra3 SCSI processors, as well as QLogic’s ISP1280 dual channel SCSI processor. The ISP10160A is a single-chip, highly integrated bus master, single-channel SCSI I/O processor for SCSI initiator and target applications. This device interfaces the PCI bus to an Ultra3 SCSI bus and contains an onboard RISC processor. The product is a fully autonomous device, capable of managing multiple I/O operations and associated data transfers from start to finish without host intervention. The ISP10160A provides power management feature support in accordance with the PCI Bus Power Management Interface Specification.
